The historical review of the evolution of accounting principles for foreign currency translation reveals that current practice is based on principles which have been developed during periods characterized by (1) wars and political instability, (2) major upheavals of the international monetary system, (3) run-away inflation with significant differences in the inflation rates of various countries, (4) relatively minor international operations in comparison with today's multitude of significant multinational business linkages, and (5) a perception of international operations as being "foreign"-in the original sense of that word-to U. S. companies.
